CONVERGYS NEWS RELEASE

Convergys Announces Sale of its Human Resources Management

Line of Business to NorthgateArinso

(Cincinnati & Atlanta; March 4, 2010) — Convergys Corporation (NYSE: CVG), a global leader in relationship management, announced today it has signed a definitive agreement to sell its Human Resources Management (HRM) line of business to NorthgateArinso, a leading global human resources software & services provider, for approximately $85 million in cash at closing and $15 million in cash over three years.

With its world headquarters in the United Kingdom, NorthgateArinso has offices in 31 countries on five continents delivering services in over 70 countries through a network of eight Service Delivery Centers. NorthgateArinso’s approximately 5,000 staff members serve more than 20 percent of the FORTUNE Global 500 companies, and it is one of the five largest HR service providers in the world.

Convergys and NorthgateArinso believe this transaction represents a unique opportunity for Convergys’ HRM clients and employees to become part of a larger, dynamically focused entity with a strong record of accomplishment in the HR services business. NorthgateArinso will offer employment to the approximately 2,300 employees of Convergys’ HRM line of business.

“This sale is a major step forward for our HRM clients because NorthgateArinso is a global leader committed to investing in the HRM business. Combining the assets of both companies is transformational and will create one of the top HR specialist companies in the world,” said Jeff Fox, president and CEO of Convergys. “This transaction with NorthgateArinso provides an opportunity for Convergys to focus our investments and efforts on growing our Customer Management and Information Management businesses.”

Convergys expects the transaction to close in the second quarter, once all customary consents and regulatory approvals are received. Jefferies & Company, Inc. acted as exclusive financial advisor to Convergys.

Transaction Impact on Guidance

To provide a more comprehensive understanding of the company’s underlying performance in 2010, Convergys is removing from its guidance for continuing operations approximately $250 million in revenues, $20 million in earnings before interest, taxes, depreciation, and amortization (EBITDA), and the $0.10 earnings per share (EPS) impact related to the HR Management line of business. Convergys now expects full year 2010 results from continuing operations to be as follows:

• Customer Management revenues of approximately $2 billion and Information Management revenues of approximately $350 million

• EBITDA of $310 million to $340 million

• EPS of $0.95 to $1.10

• Free cash flow to exceed $150 million, plus an additional cash distribution of approximately $40 million from the Cellular Partnerships

Convergys will take opportunities to further streamline the business as they are identified. Any future restructuring actions are not included in this guidance. Not included in the full year EBITDA, EPS, and cash flow guidance for continuing operations are the 2010 impact of the HRM business and this transaction, and approximately $0.05 per share for the change in the president and CEO of the company.
